Why Choose the Pizzato FX502-K221 Position Switch?
The Pizzato FX502-K221 is a compact and highly reliable industrial position switch with one-way roller actuator, designed for precise directional position detection in automation systems. As part of the established Pizzato FX series, it provides consistent switching performance and long service life in demanding industrial environments.
This model features a one-way roller lever actuator, ensuring actuation occurs in a single direction only. This is particularly beneficial in conveyor and machine applications where reverse movement must not trigger switching. Its durable technopolymer housing ensures resistance to dust, moisture and mechanical stress.
The FX502-K221 is equipped with 1 normally open (NO) and 1 normally closed (NC) snap-action contact with positive opening functionality, making it suitable for both control and safety circuits. It also features dual PG13.5 conduit entries and is designed for continuous-duty operation without a reset mechanism.
Key Advantages
- Reliable position switch with one-way roller actuator.
- Directional actuation prevents false triggering from reverse motion.
- 1NO + 1NC contact configuration for flexible control and safety circuits.
- Positive opening contacts for enhanced safety reliability.
- Compact and robust design for long-term industrial use.
- High resistance to dust, moisture and harsh environments.
Key Features
- Pizzato FX series position switch.
- One-way roller lever actuator.
- 1 NO + 1 NC snap-action contacts.
- Positive opening safety mechanism.
- Technopolymer housing with 2 × PG13.5 conduit entries.

- Zinc-plated steel components for durability.
- Silver contacts for reliable electrical conductivity.
Directional Position Detection for Industrial Systems
Position switches such as the Pizzato FX502-K221 are used to detect movement or position of machine components within industrial machinery. The one-way roller actuator ensures activation only in a defined direction, improving control accuracy and preventing unwanted switching caused by reverse movement.
The inclusion of positive opening contacts ensures safe and reliable circuit interruption, making this switch suitable for safety-related applications in industrial automation systems.
Typical Applications
- Conveyor systems with directional detection.
- Industrial automation and production lines.
- Material handling and packaging machinery.
- Mechanical position monitoring systems.
- OEM machinery and control panel integration.
- Safety circuits requiring NO and NC outputs.
